Abstract (en)

[origin: WO0023543A1] This invention relates to a lubricating composition comprising a blend of a major amount of an oil of lubricating viscosity, gear or transmission oil package and a top treatment which comprises at least one saturated fatty phosphate ester or salt, wherein the lubricating composition is free of saturated fatty phosphites. In another embodiment, the invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, at least one saturated fatty phosphate ester or salt, at least one polysulfide and at least one phosphorus antiwear or extreme pressure agent, wherein the lubricating composition is free of saturated fatty phosphites. The invention relates to additive combinations which when added to a lubricant can provide and improve frictional and, optionally, thermal stability properties. The additives include a phosphate ester or salt wherein the hydrocarbyl group of the phosphate is a fatty-saturated group. The top treatment may also include a substituted fatty imidazoline or reaction product of a fatty carboxylic acid and polyalkylene polyamine and/or a borated dispersant.
